Preheat the oven to 350. Crush your chocolate eggs in a bag with a rolling pin, mallet, or a hammer if you are as awesome as me and your neighbors already hate you from the time you smashed Lemonheads so it doesn't really matter if you do it again.

Cream the butter and sugars until the are light and fluffy. Add the eggs and vanilla. Mix all the dry ingredients in a separate bowl and then slowly add it into the wet mixture. Add the Cadbury eggs and beat a couple more times. You want to dough to be a little wet, these cookies are supposed to turn out brownie-like.
